没有创建 liquibase.change.core.RawSQLChange 的逆

Question

问题在于：当运行命令maven时，似乎问题在https://liquibase.jira.com/browse/CORE-465中找到，但是是2009年，可以用"Cannot Reproduce"标记，我使用一个文件。xml type liquibase with one changeSet，但是许多 createTable、addPrimaryKey、回滚、addForeignKeyConstraint，这个文件总是创建表和你各自的约束，但我正在回滚这个错误发生了，我厌倦了在互联网上找到，然后找不到问题的解决方案，你是吗可以解决这个问题吗？与社区分享！

此处用于 maven 的插件和命令：

liquibase:rollback -Dliquibase.rollbackTag=payScript -PproductionPostgreSql

这里的插件

<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>3.4.1</version>
    <configuration>
        <changeLogFile>${basedir}/src/main/resources/changelogs/db.changelog-master.xml</changeLogFile>
        <driver>${driver}</driver>
        <url> ${host.db}</url>
        <username>${user.db}</username>
        <password>${password.db}</password>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-core</artifactId>
            <version>3.4.1</version>
        </dependency>
    </dependencies>
</plugin>

这产生了下面的堆栈跟踪

Answer 1

这是预期的行为。在您的变更日志中的某处，您有一个使用原始 SQL 的变更集。您没有在此处包含它，但实际内容并不重要 - 只要它是原始的 SQL，Liquibase 无法确定如何 'undo' 或回滚该更改。解决此问题的方法是查看该变更集并向该变更集添加一个回滚标记，描述如何回滚所做的更改。

这里的文档http://www.liquibase.org/documentation/changes/sql.html are for the SQL tag. Rollback in general is described here: http://www.liquibase.org/documentation/rollback.html

特别注意这一段：

Other refactorings such as “drop table” and “insert data” have no corresponding rollback commands that can be automatically generated. In these cases, and cases where you want to override the default generated rollback commands, you can specify the rollback commands via the tag within the changeSet tag. If you do not want anything done to undo a change in rollback mode, use an empty tag.

这是一个显示原始 SQL 变更集和相应回滚标记的示例。

<changeSet author="liquibase-docs" id="sql-example">
    <sql dbms="h2, oracle"
            endDelimiter="\nGO"
            splitStatements="true"
            stripComments="true">insert into person (name) values ('Bob')
        <comment>What about Bob?</comment>
    </sql>
    <rollback>
        delete from person where name='Bob';
    </rollback>
</changeSet>

请注意，这是一个非常天真的例子 - 你可能不想在真实场景中使用它，因为在你有运行 liquibase update 部署此更改，即任何使用数据库的程序都可能将行插入到名为 'Bob' 的人 table 中，并且此回滚语句将删除名称为 [=27] 的所有行=].
